A street shown on the GDOT Functional Classification Map which provides access to residential and non-residential developments. Typically an existing street.
510-40.04 Collectors, Residential Developments.
Collectors are divided street designed to handle traffic volumes in excess of normal neighborhood traffic generation, that is configured as a divided street with one or two lanes of traffic in each direction. Collectors also may be provided as central routes within large residential subdivisions, where appropriate to the design, based on project traffic demands exceeding 2000 trips per day (ADT). Driveways will not be allowed along any Boulevard classification roadway.
510-40.05 Cul-de-sac Streets.

E.The length of a cul-de-sac street shall be measured from the center of the cul-de-sac back to the center of the originating intersection.
F.Circular cul-de-sacs shall conform to the layout and dimensional requirements as notated herein.
G.Landscaped island shall not be allowed unless the HOA will maintain the island and landscaping. Installation is at risk of PCDOT requiring removal and area to be paved to meet PCDOT standards. Reference Title 3 Chapter 510-30.05.B.
510-40.06 Other Dead-End Streets.
A.Stub streets shall be built in all cases where adjacent lots have potential for development and shall meet minimum standards for a Local Residential S2 Street.
B.A dead-end street shall be provided to the boundary of a subdivision where necessary to provide access to a land-locked abutting property, for planned continuity of future circulation, for improved access for public safety vehicles or for the extension of public water or other utilities to neighboring lands. Such dead-end streets shall be designed so as to allow their reasonable extension, and shall be located so as to be reasonably incorporated into a street design for the neighboring property. The stub street requirement may be waived by PCDOT under extenuating circumstances.
C.Dead end streets on abutting property shall be extended into a proposed subdivision and incorporated into the street design of the development. This requirement may be modified by PCDOT in cases of serious topographical hardship or dissimilar zoning which would create unacceptable land use conflicts between the two developments. This modification may be conditioned on the provision of easements necessary for the extension of public utilities, the provision of cul-de-sac or other permanent turnaround on the dead-end street, or the removal of the dead-end street back to its nearest intersection.
D.Where a dead-end street (other than a cul-de-sac) serves more than two lots, the developer shall be required to provide a temporary vehicular turnaround within the right-of-way. This requirement may be waived if extension of the dead-end street is approved and under construction prior to its inclusion in a final plat.
E.Where a street dead ends at the property boundary and the street exceeds 1000 feet in length, a permanent cul-de-sac shall be required. In this situation, right-of-way to the property boundary shall be required, but the pavement shall not be extended to the property boundary beyond the edge of the paved cul-de-sac turnaround. In no case shall a dead-end street exceed 2000 feet in length unless approved by PCDOT due to unusual topographic conditions or property configuration.
E.In residential subdivisions, a dead end (“stub”) street required under Section 220.20.11 to provide access to an abutting property may be exempt from construction of roadway improvements and public utilities under the following circumstances:
1.No lot within the proposed subdivision will gain access from the “stub”
street.
2.A Concept Plan has not been submitted or approved on the neighboring tract.
3.The “stub” street shall be fully designed as part of the construction plans.
However, the right-of-way shall only be cleared and rough graded in accordance with the approved plans and all disturbed areas grassed.
4.Connections for future extension of all public utilities shall be constructed as part of the subdivision. Curb returns shall be constructed as part of the subdivision. Curb returns shall be provided to the future “stub” street roadway location, and curb and gutter shall be installed across the roadway stub at the right-of-way line (extended).
5.The right-of-way for the “stub” street shall be dedicated as part of the final plat. Slope easements or construction easements, if required by the street design, shall be shown on the final plat and reference a future development connection.
510-40.07 Service Roads.
Where a development borders on or contains a railroad right-of-way, or limited access highway right-of-way or major thoroughfare, a public street may be required to be constructed and dedicated within the development approximately parallel to and on each side of such right-of-way.
510-40.08 Reserve Strips.
Land in private ownership adjacent to public rights-of-way which could control or are intended to control access to streets, alleys, or public lands shall not be permitted unless their control is given to the County under ownership, dedication, or easement conditions approved by the County Attorney or acceptable to PCDOT. No development shall be designed so as to deny access to abutting properties.
510-40.09 Alleys.
Alleys shall not be provided except where the subdivider produces evidence satisfactory to the Development Control Committee and and/or the Development Control Committee PCDOT of the need. In the event PCDOT approves a design that proposes alleys, the alley shall be constructed as though it were a local street, remain private, and PCDOT will have no maintenance jurisdiction.
510-40.10 Street Jogs.
A.Within residential developments on Street Classifications equal to or lower than S3, Streets shall either directly align or have offsets of a minimum of 125 feet as measured between radii to radii of said street.
B.Access onto the County Road network or roadways classified greater than S3 shall utilize GDOT’s Spacing Criteria for Driveways, Public Roads and Side Streets to determine the spacing if the streets cannot directly align.
